PRESSURE RELIEF VALVE
2Pages

SAPAG-0036-ENG-2302 The maximum pressures and temperatures depend on the pressure/temperature ratio, materials, size (DN) and nature of the fluid. Performance PRESSURE RELIEF VALVE Limit maximum pressure in a line by discontinuously and briefly discharging high flow. PROTECTING PIPES FROM PRESSURE SURGES Metal-to-metal sealing between nozzle and blanking plate. Quick opening: 1/40th of a second. Adjustable setpoint via spring acting directly on blanking plate. Moving part low inertia. Sealing for upstream pressure below setpoint. No guidance (no jamming or parasitic drag). Tightness and high-precision (honed radius). Safe actuation. Technical features Type of conveyed liquid: • Conditions of use Contaminated, raw or drinking water. In meshed networks with numerous nodes. Generally where surges/bursts may occur. Vertically fitted valve. As close as possible to the component creating pressure surges. Upstream from a shut-off device (valve) or overspeed valve. Downstream from pumping station pumps. Piping connector diameter at least equal to pressure relief valve diameter.
